Definitions

  • the invention relates to a mine, in particular an anti-tank installation mine with a mechanical control device which, when a signal is received from a connected electronics, rotates the rotor, which can be mechanically fixed in the safeguard, into the arming position and triggers a marker charge to indicate the state of the mine being restored.
  • a mine of the type mentioned is known from DE-B 2 423 912.
  • a device for re-securing is provided with a switching element which can be moved from the safe to the arming and from the arming to the re-securing position under the influence of a locking mechanism, to which a marker charge indicating the re-securing is assigned.
  • a signal is sent for reinsurance, which ignites the reinsurance lighter cap via control electronics. Due to the resulting gas pressure, the rotor is moved to the re-securing position, in which the firing pin and a recess serve as a ratchet.
  • the marker charge is ignited in the re-seizure that has been taken, and the explosive charge primer is also destroyed at the same time.
  • a disadvantage of such a mine is that not only the marker charge after re-securing and possibly a new battery must be used, but also that the entire re-securing device must be removed, disassembled and re-used if this mine is to be reused is provided.
  • EP-A1 0 195 182 A mine has been proposed in EP-A1 0 195 182, which has a resetting of a safety device of the mine. It is a thermally triggerable bistable reset device that acts on the detonator.
  • EP-A1 0 195 182 relates to a prior art according to Art. 54 (3) of the EPC.
  • the mine in focus can be ignited by an electrical signal from electronics associated with the mine. If, on the other hand, ignition is not to take place, which is possible both after the set time has elapsed and before the set time has elapsed, a second signal from the electronics in question gives the mine safety device the command to return to the de-energized initial state.
  • the present invention thus discloses a security device for an anti-tank laying mine, which can be reset and thus secured again and in this way makes the mine usable as often as desired.
  • Another advantage of this laying lead is the laying reliability when focusing, which is made possible by the attached gear mechanism.
  • the lead 44 shown with the housing 29 forms a substantially circular body with a surface 30 into which the battery cover 27 is embedded.
  • a rotary lever 1 can be locked in the securing of the lead 44 by a tab 28 on the lead surface and is in focus against a stop 31 on the underside of the cover or on the housing cover.
  • a nose 46 on the rotary lever 1 lies directly above the battery compartment cover 27, which cannot be opened in this position.
  • the axis of rotation of the rotary lever can be seen at 47 in FIG. 1.
  • the start of the unlocking time and thus also the start of the possible functional sequences begins with the removal of the tab 28 from the rotary lever 1.
  • the elevator device By pressing the rotary lever up to a mechanical stop, the elevator device according to FIGS. 3 and 4 is actuated in such a way that the force is passed into the clamping disc 4 via the spiral shaft 2 and the lower friction disc 3 and from there into the clamping rollers 5 .
  • the pinch rollers 5 lie against the inner wall 43 of the elevator wheel 6 and take this elevator wheel with them during the rotational movement as long as the force is supplied by the spiral shaft 2 via the axial pressure.
  • the elevator wheel 6 is in drive connection with the spring core 7, which in turn is connected to the barrel 10 and the torsion spring 9 arranged in the barrel 10.
  • the energy applied remains stored in the barrel 10 until the rotary lever 1 is turned to the arming position.
  • a mechanical spring core lock 11 is triggered, which locks the spring core 7 in the energized state.
  • a toggle switch 12 is actuated, which causes the balance 13 of the gear mechanism 8 to start up. The balance 13 swings out of the zero position.
  • the mechanical movement 8 is driven by the torsion spring 9 of the barrel 10 and expires within a predetermined time, which corresponds to a safety for people and facilities when laying the mine 44 and the activation in the arming.
  • the torsion spring 9 simultaneously pulls on the control wheel 17 the previously energetic torsion spring 15 of the control shaft 16.
  • the rotational movement of the control shaft 16 is limited by an axial pin 41 which engages in a 180 ° annular recess 21 in the control wheel 17.
  • the control shaft 16 has carried out the rotation of 180 ° in about 10 minutes.
  • the sprung core 33 of the lifting tangent 18 can now fall into a recess 34 in the cover plate 19 attached to the control shaft 16 and thus lock the control shaft 16.
  • the spring core lock 11 is unlocked via a rigid lever connection 35.
  • the residual energy remaining in the barrel 10 can be dissipated via the spring core 7 in the direction of the elevator wheel 6 until the torsion spring 9 of the barrel 10 is without energy.
  • the spring lock 11 remains unlocked. It is held in the rearmost position by the locking spring 20 (leaf spring) and only released again by the control cam 36 of the switching socket 37.
  • Mine 44 is now in wait. During this time, it is not possible to make the mine 44 unusable by turning back the rotary lever 1 or by removing the battery by removing the battery compartment cover 27.
  • the voltage present is continuously checked during the action time of the mine 44. If a sudden drop in voltage is registered, for example by turning the rotary lever 1 in the safety device, the trigger signal for the active charge is automatically given and the mine 44 ignites.
  • the signal for triggering the active charge causes the force element 23 to be ignited, as a result of which the rotor 14 is released from its fixed position.
  • the energy of the torsion spring 15 now causes, via the control wheel 24, which is arranged coaxially to the control wheel 17 on the control shaft 16, a rotation of the drive-connected intermediate wheel 25 and thus finally the rotation of the drive-connected rotor 14 into the arming position for ignition of the mine 44.
  • the signal for resetting the sprung core 33 of the solenoid 18 from the electronics 38 causes the torsion spring 15 to relax via the control wheel 17, the barrel 10 with the spring core 7 and the clutch wheel 26. After the expiry, the safety device is again in the de-energized starting position and secured. After this re-securing, the marker charge is ignited to indicate the restored state of the mine 44.
  • the mine 44 can immediately be made ready for use again and relocated. This process can be repeated any number of times.
  • the signal from the electronics 38 for the recovery of the mine 44 takes place either after the time specified in the electronics has elapsed or by a signal from a remote control or the like sent from outside.
  • a line 48 leads from the electronics 38 to a battery, not shown here, which ensures the energy supply.
  • the line 49 connects the electronics 38 to the force elements 23 and the further line 50 is a connection between the electronics 38 and the active charge.
  • the electronics 38 is connected to the solenoid 18 through line 51, to a switch 56 through line 52, to the marker charge through line 53, to the clearing charge (not shown) through line 54, and finally to a voltage monitor (not through line 55.
  • a common ground point which is known per se and is also not shown, is located on the safety device.
